Subject: [PATCH 0/6] Netfilter fixes for net

Hi David,

The following patchset contains Netfilter fixes for net:

1) Use CONFIG_NF_TABLES_INET from seltests, not NF_TABLES_INET.
   From Naresh Kamboju.

2) Add a test to cover masquerading and redirect case, from Florian
   Westphal.

3) Two packets coming from the same socket may race to set up NAT,
   ending up with different tuples and the packet losing race being
   dropped. Update nf_conntrack_tuple_taken() to exercise clash
   resolution for this case. From Martynas Pumputis and Florian
   Westphal.

4) Unbind anonymous sets from the commit and abort path, this fixes
   a splat due to double set list removal/release in case that the
   transaction needs to be aborted.

5) Do not preserve original output interface for packets that are
   redirected in the output chain when ip6_route_me_harder() is
   called. Otherwise packets end up going not going to the loopback
   device. From Eli Cooper.

6) Fix bogus splat in nft_compat with CONFIG_REFCOUNT_FULL=y, this
   also simplifies the existing logic to deal with the list insertions
   of the xtables extensions. From Florian Westphal.

Diffstat look rather larger than usual because of the new selftest, but
Florian and I consider that having tests soon into the tree is good to
improve coverage. If there's a different policy in this regard, please,
let me know.
